The transverse branch :6 of this fittingiex-ltends horizontally and isconnected to'receive under pressure from any suitable 7 source the waterwhichi is toibe mixed with the ozone or .ozonous .air. The. longitudinaland vertical branch 7 of the fitting is provided with flanges 3'8 and '9and the upper end thereof-is closed-by a, late 10,:whic is clamped tothe flange 8 be p "Its 11. A:-washer=1-2 of rubber or any ot er suitablematerial is, interposed between the plate :10 .and' the flange 8 to sealthe joint; j A ring :13. which'is provided with end fianges'l'iand15andtapers downwardly is secured to the lower end 0 he longitudinalbra-nchi7 by bolts lfi which are carried by the flange 9 andextendlthroughe thexflan a 14. A'washer. 17- is interposed between theanges 9 and 14 for sealing pur oses. The lower end of the ring vJ13icommunlcateswith a tubular tapers' inwardlg and forms with saidring a wich corresponds in shape to casing-'18'is flared outwardlyvtoiorma 00-element or casing 18,th eupperend 19 of which noidal chamber 22 whichcommunicates with the chamber and is adapted to discharge or exhaustinto a pipe connection 23 which is provided at its upper end with aflange 24. The upper and lower ends of the casing member 18.are providedwith outwardly extending flan es 25 and 26. The contiguous faces of theflanges 15 and 25 and the flanges 24 and 26 are provided withcirculargrooves 27 in each pair of which is disposed a packin rin 28 which ispreferably formedof oil leat er and operates to sealefi'ectively thejoints.

The ozone is delivered to the casing through a ipe 29 which extendsthrou h a circular ho e 30 in the central ortion 0 the plate 10. Toprevent leakageo water around the. pipe 29,,a packing land is provided.This gland comprises a It operated follower 31 and a acking receiver 32which is formed integr l with the plate 10. The pipe 29 extends t roughthe longitudinal branch 7 of the T-fitting and the ring 13 and its lowerend projects into the chamber 20 and terminates adjacent the portion ofthe tubular member which is of the smallest diameter. The lower endof'the pipe is flared outwardly as at' 33, so as to form with the upperend 19 of the member 18 a comparatively wide tubular water conduit thesides of which converge downwardly or toward the lower end of the pipe29. y constructdischarge end as set forth, the water is spread outover acomparatively lar e area, i. e. it is formed from a comparative y thickstream into a relatively'thin one. Furthermore the velocity of the wateris increased'while its direction remains unchanged.

The lower edge of the ipe 29 tapers inwardly to form a conoida surface34. .Adjacent this surface and coaxial with the pipe 18! spreader 35 theupper end 36 of which conforms in shape to said surface and formstherewith a circular passageway 37 which directs the ozone from the pipe29 downwardly and outwardl As the tubular stream of water passes li ythis passageway it exhausts the ozone from the ipe 29 and brings. itinto contact and afliliation there'- with try-aspiration. Acharacteristic "and a result of utilizing a circular substantially unobstructed passageway forthe ozone or gas and a comparatively widetubular column of water-"or liquid which is forced in a thin stream pastthe passageway is that the aspiration efiect is a maximum and the gas isthoroughly and uniformly commingled with the water.

The spreader is disposed in the chamber 22 and itsside walls 38 areround and taper downwardly so as to form with. the lower end 21 of thecasin member a tubular water conduit into whic the commingled water andozone discharges. The sides of this conthe water passage andconstricting itsv duit diverge downwardly and as a result the waterspreads so that a thorough mixing oi the water and ozone takes place.The diameter of the upper end of the spreader is slightly smaller thanthe diameter of the outer and. lower edge. of the pi 29 so that thetubular stream of water W1 1 not splash into contact therewith. Theupper end of the spreader is sup r'ted bya bolt 39. The lower end ofthis be t-is embedded in a socket 40 which is formed in the spreader andthe upper end extends through a spider 41 which extendstransversely'across and is secured to pipe 29. A nut. 42 is threaded tothe extreme upper end of the bolt. B rotating this nut the spreader maybe adjusted longitudinally into the desired position. The lower end ofthe spreader is provided with a concave socket 43 into which fits acorrespondingly convex supporting element 44 which is provided withoutwardly extending arms 45 which are formed integrally with the pipe.connection 23. A bolt 46 is anchored to the lower end of the spreader 35and extends longitudinally through the su porting element 44. The lowerend of this bo it is provided with a nut 47 which when tightened o testohold the spreader against lateral displacement. By having the contiguousfaces of the su portingelement and socket 43 convex an concaverespectively, the spreader will automatically center itself whenpulleddownwardly by the nut 47.

The spider41, bolts 39 and 46, and nuts 42 and 47 are preferably formedof nickel so that only a limited amount of oxidation will take placedue' to their contactwith the ozone.

he pipe 29, the spreader 35, the casing 18, and the pipe connection23and its supporting element 44 are all formed of glass, terra cotta orany other similar non-oxidizing ma terial. The casing memberl8 isclhmped between the ring 13 and the pipe connection 23 by meansoftiebolts 48 which extend throueh the flange 15 and a metallic collar 49.The

latter extends around the pipe connection 23 and abuts against the flan24. By tightening the nuts on the tie olts the packing rings 28 may .becompressed to form fiui tight connections or joints.

To protect the glass or terra cotta pipe29 against the impact andressure of the lateral stream of water to whic it issubjected, a air ofsemi-cylindrical; sections 50 are provided. These sections arepreferably formed of galvanized sheet iron and extend around the ipe toform a cylindrical protecting shell w ich extends from the plate 10. tothe base of the flared end of the ozone pipe. Spring steel rings. 51encircle the shel and press the sections 50 into abuttingrelation andcontact with the pipe 29. A band 51 also encircles the sections and issuitably secured thereto against longitudinal movement. A plurality ofbraces 52, preferably four in number, ex:

tend between band and wall of the ring 13. These braces extend upwardlyand operate tosupport the i pipe .againstilthe abut aga nst the band andringirespectively and a sleeve'54-to whichthe members are threaded. YThe braces maybe lengthened or shortened to center-and position the ipewith. respect to the casing 18by rotatingt esleeves 54'. To preventdisplacement] :of the braces the outer members v53 are provided at;their outer ends with socket members which'fit the tubularstream ofliquid formedby said intorecesses in thejwall ofthe ring.

A discharge piper56 isconnecbed to-theow erv'end of the .pipe'connectionv23 by a-sleeve 57 which is packedwith cement.

lows Assuming that the pipe -29 i's connected to receive ozoneor-ozonous air and that the sageway '37 the mixedwater and ozone passesinto the expanding conduit where it-spreads branch 6 of the fitting isconnectedtoreceive water under pressure, the water will be'forced intothe longitudinal branch 7 and vthence downwardly into the ring 13 whereitrwill be confined and forcedthrough-the tubular and constrictedconduit. The latter :tendsto Lin crease the velocity of the waterandtoform it into a thin relatively wide annular'stream which istprojected past the circular ozone passageway 37 and there draws theozone into contact with it byaspiration; From the pas and thoroughlycomminglesfandgmixes with the ozone. In assembling the mixer',L-thepipe29 is centered with respect tothe casinglS by adjusting the braces 52.Thereafter the spreader is-positionedto-"meet the, desired requirements.by adjusting the nut ,42 and then tightening the nut 47" tojam'thespreader into position. Duringthis lastmentioned operation theconcave and convexs'urfaces automaticallycoact tocenter the spreader. 1The invention exemplifiesa device for, mixinga gas and liquid byaspiration which is of new andimproved construction and: is, especiallydesigned and adapted for use in connection with water and ozone.
